A. CORPORATION OF DELAWARE BOBBIN. i.

Application led September VTo all whomiizf may conce-rn:

Be it known that I, ANDREW STADLER, a citizen of the United States, and a resident of Trenton, in the county of Mercer and to receive threads of different kinds and has for an object to provide an improved construction wherein. the thread may be dampened or otherwise treated to prevent kinking or curling as the thread is unwound from the spool.

Another ob]cctof the invention is to provide a spool formed with means whereby a treating liquid or other treating matter may be applied exteriorly and interiorly of the thread wound on the spool.

In the accompanying drawing- Figure 1 is aside view of a spool disclosing an embodiment of the invention, certain parts 'being broken away for illustrating certain parts of the invention in a better manner.

FigureQ is an in Figure 1. f

Figure 3 is a sectional view through Figure 1, approximately on line 3 3.

Referring to the accompanying drawing by'numerals, 1 indicates the bo'dy of a spool and 2 and 3 the ends, which are removably mounted on the body'l, said ends being held in place by any desirable means, as for instance, screws. The body 1 may be made of any suitable material, as for instance, hard wood, metal or some material which will not be readily affected by water or steam. The ends 2 and 3 are also made from rubber, 'metal`l or other suitable material. rIhe bobbin is intended to be used in factories where the thread isl laid from the spool to the loom'or other device using the thread. The thread on leaving the spool must bein such a condition as not to kink orv become snarled. Where the silk, wool, 'cotton or other thread is comparatively heavy, the tendency to kink as the thread moves is increased. -eforethe thread can be properend' viewof thle spool shown ao, 1923. serial m. 663,387'.v

ly used, it must'be straight and dead and in order to bring the thread to this condition heretofore, the thread hasbeen soaked for a longtime, as forI instance, twelve hours in water or subjected to steam for an appreciable time, which steam oftentimes burned part of the thread as heretofore it was com;- pelled to penetrate the thread on the spool from the exterior surface.

In thespool shown vin the drawing, means have been provided whereby the thread may be killed by water or steam applied exteriorly and also interiorly.` As indicated in the drawing, the body 1 is provided with a num.- ber of spiral grooves 4 and a number of radiating apertures 5 radiating from a central longitudinal bore 6. Some of the `apertures 5 open or discharge in to the grooves 4 while others extend to the periphery of the body 1. 'Each ofthe ends 2 and 3 is provided with an opening 7 corresponding to the cross` sectional area of the respective grooves andarranged so that there will be one opening registering with each groove whereby water may be forced from one end to the other through these openings and thc respective grooves 4. In addition,water may bepassed through the bore 6 and out through the radial openings 5. Where the bobbin with its thread is merely soaked in water, the water will penetrate the thread from the outside inwardly and also fromthe various grooves 4 and tion outwardly.

Where steam is used the same method may be followed of applying it inwardly and apertures 5 in a direc- I outwardly whereby the .threadf is soaked or killed more uickly than where an ordinary spool is used without the grooves 4 and apertures 5. It will, therefore, be seen that -regardless of what method is used for killing heavy` twisted thread, the argrooves extending the length of said body and terminating in openings in said end members.

2. A bobbin, comprising a body having 5 helically arranged grooves extending from one end to the other, a pairv of removable end members, each of said end members having an aperture registering with each of the grooves whereby liquid muy be forced through the apertures in one of the end 10 members, along said grooves and out the aperturesin the opposite end member.
